Abstract: A process is provided for selectively removing sodium ions from a solution containing sodium and ammonium ions using a polysulfonated aromatic cation exchange resin. The polysulfonated resin exhibits enhanced selectivity for sodium ions over ammonium ions when compared with conventional, monosulfonated cation exchange resin. This enhanced selectivity results in a lower concentration of sodium ion leakage and longer bed life to critical leakage, compared with conventional, monosulfonated resins.

The inventive method is distinguished in that blanks for edge protecting means (7) are fed as a continuous band (7a) which when advanced is preliminary bent around a longitudinal line, that the fed-out portion of the band (7a) is cut to form an edge protecting means (7) in correct position, and that the edge protecting means (7) is finally bent in connection with cutting. The inventive device is characterized in that a magazine containing blanks for edge protecting means in the form of a band (7a) is secured to a body (6) supporting a feeding mechanism (8-17) for said band which comprises means (8) for preliminary bending the band (7a) around a longitudinal line, a cutting means (30) being fixed to the body (6) serving to separate, after feeding the band a predetermined distance, the fed-out portion of the band as an edge protecting means (7), a bending means (30, 32) thereby being arranged to finally bend the edge protecting means (7) on separation thereof.

Patent NL-92405-C (NL)
IPC: B29C48/05
Granted: 1900-01-01
Abstract: <PICT:0823261/IV (a)/1> In melt-spinning apparatus of the type in which the molten material is supplied by a screw-type extruder to a positive displacement metering pump of the rotary gear type, the driving shaft of the metering pump is driven by the screw of the screw type extruder or pump, the drive being taken from the end of the screw at the discharge end of the screw pump and the coupling or other drive from the screw to the metering pump being enclosed in a casing or housing, the free space in which communicates with the free spaces in the screw pump and metering pump casings respectively and the joints between the drive casing and the screw pump and metering pump casings respectively being liquid-tight. As shown in Fig. 1, grains of polymer 2 in the supply vessel 1 are melted by the spiral tube melting grid 5 to which a heating fluid is supplied through the inlet end 6 and thereafter flows through the heating jacket 9 surrounding the melt receiver 8 and the heating jacket 20 surrounding the casing 13 of a screw pump 12. The melt flows through channels 10, 11 to the screw pump 12 in which the melt is moved towards the discharge port 25 by the screw 14 integral with the shaft 15 carrying the gear-wheel 16.  The melt is pumped under pressure through the discharge port 25 and inlet 26 to the metering pump 27 which supplies the melt through duct 34 and filter 35 to the monofil spinneret 38. The discharge end of the screw 14 is integral with a journal 24 provided at its free end with a groove 31 and rotatably mounted in the bore 23 in the closure 21 attached to casing 13 by bolts 22.  The tongue 30 at the free end of the shaft 29 of the gear pump 27 fits into the groove 31.  The pump 27 is attached to the closure 21 by bolts 28. Melt leaking out of the pump 27 is immediately picked up by the fresh melt at the discharge end of the screw pump and is at once returned to the gear pump together with fresh melt.  Decomposition and carbonizing of melt due to long residence in the pump assembly are thereby prevented and the gear pump does not require a packing gland.  In the other illustrated embodiment of the invention the melt is delivered by the screw pump to three metering gear pumps in parallel via a liquid-tight housing containing a gear-wheel coupled to the discharge end of the screw pump screw and mounted on the drive shaft of one of the gear pumps and also gear-wheels mounted on the shafts of the other two gear-pumps.  The first gear-wheel drives the other gear-wheels either directly or through intermediate gearwheels, all the gear-wheels being in the same plane.

Inventor: JENSEN PREBEN B
IPC: G01S7/493
Filed: 1989-08-09
Abstract: A chirped backscatter filter 10 compares a received signal (RSIG) to a reference signal related to a transmitted signal (TSIG) and removes from RSIG the frequency component which is equal to TSIG in frequency. This removed frequency component corresponds to the frequency of the transmitter backscatter radiation. The filter of the invention adds a frequency offset (fn) to both RSIG and TSIG in mixers 12 and 14 before substracting one from the other in mixer 22. Thus, equal frequency components in both RSIG and TSIG, such as the backscatter radiation frequency component of RSIG, will equal fn. The frequencies resulting from this subtraction are thereafter passed through a notch filter 24 which is centered on fn and which passes all frequency components except fn. The output of the notch filter thus no longer has a frequency component associated with the backscatter frequency component. The loss of the RSIG phase reference due to the phase reference between the RSIG and TSIG modulation envelopes being destroyed during the backscatter filtering process is therafter compensated for by adding TSIG to the filtered difference frequency component, thereby reestablishing the phase relationship of the original RSIG frequency components minus the backscatter frequency component.
